In the “Play Points” mode you should try to obtain as much points you can annihilating blue (3 points), orange (2 points), green (1 point). After each 10 moves a black tile appears reducing the active board area and after each 10 points achieved a black tile is removed from the board. The black tiles can be moved but not combined. The game ends when there are no more moves available.
In the “Play White” modes (L1, L2, L3, with timer) the aim of the White games is to get a completely white checkerboard. Try getting an empty board in the fewest number of moves in L1, L2 and L3 mode or in less time possible in the ‘with timer’ mode.
